gen17 - make a transfer function using Chebyshev polynomials
makegen(table_number, 17, table_size, index, harmonic1, ... harmonicN)
Call makegen from a script with a function_type of 17 to make a function table using Chebyshev polynomials. Use this kind of table as a transfer function with waveshaping instruments.
Unlike other gens, gen 17 never rescales the table to fit between -1 and 1.
makegen(3, 17, 1000, 0.9, 0.3, -0.2, 0.6, -0.7)
solves a Chebyshev polynomial with an index of 0.9 and four harmonics.
